Cross Connection Control
Maintaining & Protecting Your Backflow Prevention Device
The primary objective of the Cross Connection Control Program is to protect the public potable water system at the service connection by containing within the consumer’s premises any actual or potential pollution or contamination which may result from backflow through cross connections.
The Cross Connection Control Program oversees and monitors the installation, testing and maintenance of approximately 10,000 backflow prevention assemblies currently within the Water Services area. Although it is the customer’s responsibility to test these devices annually and properly maintain their backflow prevention assemblies, the Cross Connection Control Program staff works closely with the Orange County Health Care Agency, the city’s Building Department, consultants and contractors to ensure that the proper backflow prevention assemblies are installed and are tested annually.
What is a Cross Connection?
Any actual or potential connection or structural arrangement between a public or a consumer’s potable water system and any other source or system through which it is possible to introduce into any part of the potable system and used water, industrial fluid, gas, or substance other than the intended potable water with which the system is supplied. Some examples of cross connectors are:
- Bypass arrangements
- Jumper connections
- Removable sections
- Swivel or change-over devices
- Other temporary or permanent devices through which or because of which backflow can occur
Backflow Prevention Assembly
A backflow prevention assembly is an approved device assembly used to prevent backflow into the potable water system.
Annual Backflow Prevention Device Testing Requirements
The Safe Drinking Water Act Amendments of 1986, the California Code of Regulations, Anaheim Municipal Code, and Anaheim Public Utilities Cross Connection Control Program require that water users, at locations where backflow prevention devices are installed, must be tested annually and if needed, repaired by the water users and retested. The annual tests must be performed by a backflow prevention device tester certified by the Orange County Health Care Agency and has a valid City of Anaheim Business License. You may only use a backflow tester that is on the city’s approved list. You may download the approved backflow prevention device testers list (PDF) as well as the annual backflow prevention device test and maintenance report (PDF).
